MACHINE FOR STIRRING MALT.

SPECIFICATION forming part of Letters Patent No. 240,624, dated April 26, 1881.

l Application filed January 22, 1881. (No model.)

To all whom it may concern Be it known that we, ATWOOD VANE and DANIEL GUNDELFINGER, both of the city of St. Louis, Missouri, have invented a certain new and useful Improvement in Machines for Stirring Malt, Grain, &c., of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Our invention relates to an apparatus for stirring malt, grain, 8220., to facilitate its drying, and particularly to those devices in which rotary shovels traversing the room from end to end are employed.

Our improvement consists in an apparatus of peculiar construction, as hereinafter described. I

In the drawings, Figure l is a horizontal section of our invention on the line 1 1, Fig. 2. Fig. 2 is an elevation of same, one side of the room being removed. Fig. 3 is a section at at, Fig. 1. Fig. 4 is an end view of the shovels, showing them attached to the block which connects them to their carryingshaft. Fig. 5 is a side view of one of the carriages. Fig. 6 is an end view of the same, showing a section of one of the tracks. Fig. 7 is a modification of the shovels shown in Fig. 4.

A is a room, box, or bin, which may be of any desired size for containing malt or grain of any kind.

b b and b b are brackets, rigidly secured to the end A of the room A by bolts or otherwise. The brackets b b support a shaft, B, turning in boxes 11 The brackets b b support a shaft, B, turning in suitable boxes, b

On the shaft B is a pulley, O, by which a reversible power is applied to the shovel, as hereinafter explained.

On each end of the shafts B and B are pul- --leys b b and 12 b respectively, for the purpose hereinafter set forth.

D D" are carriages, of which there are two, one at each side of the box, which support in suitable bearings a shaft, E, carrying the shovels F. The shovels F are secured to the shaft E in any way desired. We have shown a block, F, secured to the shaft and having concave faces to receive the cylindricallyshaped shovels, which are attached to the block by screws, as shown in Figs. 4 and 7. We have shown four shovels F, but do not confine ourselves to this number. 3

The carriages D D are supported on grooved wheels (I, which travel on a suitable track, 0, secured to the floor of the room A. I

The shaft E has on one end a gear-wheel, G, which engages with a cogged rack, H, supported at the sides of the box or room A. Two of these gear-wheels, one on each end of the shaft E, as shown, and two cog-racks, H, may

be used when desired. This is generally the case when the box or bin is too widefor a single wheel and rack to do the work with ease.

At the end A of the box or room A are shafts I I, working in suitable boxes, 6 on brackets 11 i and i 43, secured to that endof the box. The Shafts I Icarry, respectively, pulleys i i and i at their ends.

J J are ropes or chains connected by the ends to each end of the carriages D D. The rope or chain J is connected by one of its ends to the carriageD, and is carried from thence to pulley b on the shaft B, under which it passes; thence up over pulley on shaft B; thence to the other end of the room A to pulley '5 on shaft 1, over which it passes, and down to the pulley i on the shaft I, under which it passes, and from thence tothe other end of the carriage D, where it is made fast. The rope or chain J passes inlike manner from one end of the carriage D,.under and over its respective pulleys, and back to the other end of the carriage. We haveshown the ropesas detachably secured to the carriages, so that new ones may be readily substituted.

When ropes are used, we prefer to wrap them once around the pulleys on the driving-shaft B, as shown in Fig. l, to keep them from slipping. When chains are used, the common chain-gear wheels or pulleys are provided.

To tighten the ropes or chains J J, we form the brackets 11 b and i i with slots, through which the connecting-bolts of the boxes, in which the shafts B B and I I have bearing, pass. On the ends of these brackets are lugs receiving set-screws K. Thus it will be seen that after the ropes or chains have been put'on they are tightened by turning the set-screws K, after which the connecting-bolts may be screwed up tight.

In Fig. 7 is shown a modification of the shovels F, in which they are shown to be of decreasing sizes.

The operation of the device is as follows: The ropes or chains having been applied to the carriages and pulleys, as explained, power is applied to the pulley O on the shaft B. Now, supposing the stirrer to be in the position shown in'Figs. l and 2, the pulley G will be turned to the right, which will draw the stirrer toward the pulley, the carriages traveling on the track in the room, as described. As the gear-wheel on the shaft of the stirrer engages with the cograck, it will be seen that the stirrer will be made to rotate the shovels, gathering up the material in front and dropping it over behind. When the stirrerhas thus-traversed the room in this direction the power is reversed on the pulleyO and the stirrer-made to trave'lin the other direction, the shovels, of course, turning in the opposite direction.

it will be seen, on referring to Fig. 2, that the cogs on the rack H, into which the gearwheel Gr meshes, do not reach quite to the end A of the room A. As the gear-wheel leaves thisendof the rack it engages with a pinion, L, whose shaft L has easy rotation in either direction in suitable boxeson brackets l. it will be seen that the stirrer will not be al- Thus lowed to rise 0E its plane when it leaves the rack. This arrangement is made so that when the gear-wheel leaves the rack it will revolve several times before the power is spent, thus thoroughly stirring the grain at the extreme end of the room. We have shown two of these pinions; but one may be used Where the'box IS narrow.

Having thus described our invention, what we claim as new therein, and desire to secure by Letters Patent, is-

1. The stirring apparatus consisting of track 0, carriages D D, shaft E, shovels F, cogwheel G, cog-rack H, ropes or chains J J, shafts B B I I, having suitable pulleys, b b i i and drive-pulley O, in combination with a room, A, as set forth.

2. The slotted brackets b b t z", shafts B B I I, having suitable pulleys, Nb 6 i mounted on suitable boxes, and the set-screws K, in combination with the ropes or chains J J, rotary shovel E, cog-wheel G, cog-rack, carriages D D, track 0, and room A, asset forth.

3. The pinion L, supported-on bracket-Z, in combination with cog-wheel G, cog-rack H, and ropes or chains J J, as set forth.
